BACKGROUND OF THE INVENTION

A. Field of the Invention

The present invention relates generally to topical skin care compositions.

B. Description of Related Art

Ageing, chronic exposure to adverse environmental factors, malnutrition, fatigue, etc., can change the visual appearance, physical properties, or physiological functions of skin in ways that are considered visually undesirable. Examples of such changes include reduced skin elasticity, reduced skin firmness, increased sagging of the skin, development of lines and wrinkles, development of pits or nodules in skin, development of age spots, dry skin, etc. Current products on the market either do not provide a sufficient treatment option or require a multitude of different compositions to treat these physiological changes to skin.

DESCRIPTION OF ILLUSTRATIVE EMBODIMENTS

In today's image conscious society, people are continually looking for a product that can improve the visual appearance of their skin. Often times, ageing, chronic exposure to adverse environmental factors, malnutrition, fatigue, etc., can change the visual appearance, physical properties, or physiological functions of skin in ways that are considered visually undesirable.

Typically, cosmetic compositions focus on improving the visual appearance of facial skin at the exclusion of other skin that can be exposed to the same if not more adverse environmental factors. Such skin includes hand skin and skin in the décolleté region (e.g., neck, upper chest, and shoulders), which is oftentimes uncovered by clothing and not protected or treated with topical skin formulations. Combined ultraviolet light and adverse environmental exposure of hand and décolleté skin makes such skin highly susceptible to the visible signs of aging (e.g., loss of skin elasticity, sagging skin, fine lines and wrinkles, age spots, etc.).

Accumulated exposure to UV radiation and environmental pollutants cause the breakdown of healthy collagen fibers and the production of abnormal elastin. Further, ultraviolet (UV) rays can damage melanocytes (skin cells that produce pigment or melanin). Melanocytes, which are located in the skin's epidermis, produce melanin to provide normal skin color. Ultraviolet light exposure triggers the melanocytes to create darker pigment to protect the deeper skin layer, the dermis and the subcutaneous tissue. Once damage occurs, the affected melanocytes may not produce normal skin color. The melanocytes stop producing the normal amount of pigment and create extra pigment. The extra melanin results in random dark spots scattered on the damaged skin (e.g., age spots, which are also referred to as solar lentigines, liver spots, dark spots, brown spots, discolored spots, freckles, etc.). Age spots are collections of melanin in the upper layer of the dermis, and are evidence that free radical damage has occurred. Age spots typically develop in people with a fair complexion but can be seen even in those with darker skin.

The inventors discovered that a unique combination of skin active ingredients, moisturizing agents, and sunscreen agents that can protect and hydrate the skin, revitalize and rebuild the supportive dermal matrix of skin, and reduce uneven pigmentation on the hands and in the décolleté area. When this combination of ingredients is placed in a dermatologically acceptable vehicle, the end result is a topical skin care composition that can treat or prevent a wide range of skin conditions ranging from reduced elasticity, reduced firmness, increased sagginess, dryness, flakiness, fine lines and wrinkles, pits or nodules, damage caused by ultraviolet radiation, age spots, etc. This can be achieved in a single topical skin care composition.

These and other non-limiting aspects of the present invention are described in further detail below.

A. Skin Active Ingredients

Skin active ingredients that can be used in the compositions of the present invention include (but are not limited to) euterpe oleracea fruit extract, punica granatum extract, caprooyl tetrapeptide-3, tocopherol or tocopherol acetate, and/or niacinamide. In particular aspects, the punica granatum extract can include punica granatum sterols.

Descriptions of each of these ingredients can be found in the International Cosmetic Ingredient Dictionary and Handbook, 12^(th) Edition (2008) (“CTFA Handbook”), the relevant pages of which are incorporated by reference. Further, the CTFA Handbook also provides a list of companies that supply these ingredients. By way of example, euterpe oleracea fruit extract can be obtained from Amax NutraSource (Eugene, Oreg. USA) or Assessa-Industria (Brazil). Punica granatum sterols, can be obtained from Active Concepts (Lincolnton, N.C. USA). Punica granatum fruit extract, seed extract, pericarp extract are also available for purchase, suppliers of which are listed in the CTFA Handbook. Supplies for tocopherol, tocopherol acetate, and niacinamide are commercially available through a wide range of suppliers. Caprooyl tetrapeptide-3 is a four length amino acid peptide linked to caproic acid. This ingredient is commercially available through Atrium Innovations Inc. (Canada) under the trade name CHRONOLINE™.

For the plant extracts, the inventors contemplate that any part of the plant can be used to make the extract. Non-limiting examples include extracts obtain from the whole plant, leaves, stems, flowers, flower buds, bark, roots, fruit, seeds, and any mixture of such parts. By way of example, the extract can be obtained from the whole fruit (e.g., fruit pulp and seeds), the whole plant (e.g., the entire plant is used to produce the extract), a particular part of the plant at the exclusion of another part (e.g., seed extract isolated from other parts of the plant), etc. The extract can be water-based, alcohol-based, oil-based, gel-based etc.

In addition to purchasing the plant extracts, a person of ordinary skill can also be able to isolate them by using any suitable method known in the art. In one non-limiting example, the whole plant (or any part of the plant—e.g., leaves, stems, bark, roots, fruit, flowers or flower buds, fruit, seeds, seed pods, etc.) can be disrupted by mechanical means which results in a puree. The puree can then be processed to be substantially free of impurities or undesired solids. The puree can then be poured into a shallow vessel and quickly exposed to low temperature, i.e., flash frozen, for example at −20° C. or lower, under a vacuum for removal of water content (lyophilization). The resultant extract can then be used in the compositions of the present invention.

B. Moisturization Agents

The inventors also discovered that a combination of glycerin and butyrospermum parkii (shea butter) along with the above mentioned skin actives produces a stable composition having excellent moisturization properties. Both glycerin and butyrospermum parkii (shea butter) are described in the CTFA Handbook along with corresponding suppliers of such ingredients. Additional moisturizing ingredients that can be used with the compositions of the present invention are described below.

C. Sunscreen Agents

An additional discovery of the inventors is a combination of sunscreen agents that remain photo-stable when used in combination with the skin actives, moisturizing agents, and dermatologically acceptable vehicle. This allows for a stable and prolonged period of protection from ultraviolet rays after topical application to skin. The following combination works well with the compositions of the present invention: 2-ethylhexyl 2-hydroxybenzoate (also known as octisalate), (2-hydroxy-4-methoxyphenyl)-phenylmethanone (also known as oxybenzone or benzophenone-3), 2-ethylhexyl 2-cyano-3,3-diphenyl-2-propenoate (also known as octocrylene), and 1-(4-methoxyphenyl)-3-(4-tert-butylphenyl)propane-1,3-dione (also known as avobenzone, butylmethoxydibenzoylmethane, or 4-tert-butyl-4′-methoxydibenzoylmethane). Each of these sunscreen agents are described in the CTFA Handbook along with corresponding suppliers of such ingredients.

Additional sunscreen agents that can be used with the compositions of the present invention are described below.

By varying the —Si—O— chain lengths, side groups, and crosslinking, silicones can be synthesized into a wide variety of materials. They can vary in consistency from liquid to gel to solids.

The silicone containing compounds that can be used in the context of the present invention include those described in this specification or those known to a person of ordinary skill in the art. Non-limiting examples include silicone oils (e.g., volatile and non-volatile oils), gels, and solids. In preferred aspects, the silicon containing compounds includes a silicone oils such as a polyorganosiloxane.

Other non-limiting volatile silicone oils that can be used in the context of the present invention include those available from General Electric Co., Silicone Products Div., Waterford, N.Y. and SWS Silicones Div. of Stauffer Chemical Co., Adrian, Mich.

vii. Essential Oils

Essential oils include oils derived from herbs, flowers, trees, and other plants. Such oils are typically present as tiny droplets between the plant's cells, and can be extracted by several method known to those of skill in the art (e.g., steam distilled, enfleurage (i.e., extraction by using fat), maceration, solvent extraction, or mechanical pressing). When these types of oils are exposed to air they tend to evaporate (i.e., a volatile oil). As a result, many essential oils are colorless, but with age they can oxidize and become darker. Essential oils are insoluble in water and are soluble in alcohol, ether, fixed oils (vegetal), and other organic solvents.

Example 3 Additional Assays that can be Used to Test Compositions

The efficacy of the compositions of the present invention can be determined by methods known to those of ordinary skill in the art. The following are non-limiting assays that can be used in the context of the present invention. It should be recognized that other testing procedures can be used, including, for example, objective and subjective procedures.

Skin Firmness and Elasticity Assay with a Hargens Ballistometer: Skin firmness and elasticity can be measured using a Hargens ballistometer, a device that evaluates the firmness and elasticity of the skin by dropping a small body onto the skin and recording its first two rebound peaks. The ballistometry is a small lightweight probe with a relatively blunt tip (4 square mm-contact area) was used. The probe penetrates slightly into the skin and results in measurements that are dependent upon the properties of the outer layers of the skin, including the stratum corneum and outer epidermis and some of the dermal layers.

Skin Softness/Suppleness Assay with a Gas Bearing Electrodynamometer: Skin softness/suppleness can be evaluated using the Gas Bearing Electrodynamometer, an instrument that measures the stress/strain properties of the skin. The viscoelastic properties of skin correlate with skin moisturization. Measurements can be obtained on the predetermined site on the cheek area by attaching the probe to the skin surface with double-stick tape. A force of approximately 3.5 gm can be applied parallel to the skin surface and the skin displacement is accurately measured. Skin suppleness can then be calculated and is expressed as DSR (Dynamic Spring Rate in gm/mm).

Skin Moisture/Hydration Assay: Skin moisture/hydration benefits can be measured by using impedance measurements with the Nova Dermal Phase Meter. The impedance meter measures changes in skin moisture content. The outer layer of the skin has distinct electrical properties. When skin is dry it conducts electricity very poorly. As it becomes more hydrated increasing conductivity results. Consequently, changes in skin impedance (related to conductivity) can be used to assess changes in skin hydration. The unit can be calibrated according to instrument instructions for each testing day. A notation of temperature and relative humidity can also be made. Subjects can be evaluated as follows: prior to measurement they can equilibrate in a room with defined humidity (e.g., 30-50%) and temperature (e.g., 68-72° C.). Three separate impedance readings can be taken on each side of the face, recorded, and averaged. The T5 setting can be used on the impedance meter which averages the impedance values of every five seconds application to the face. Changes can be reported with statistical variance and significance.

Skin Dryness, Surface Lines, Skin Smoothness, and Skin Tone Assay: Skin dryness, surface fine lines, skin smoothness, and skin tone can be evaluated with clinical grading techniques. For example, clinical grading of skin dryness can be determined by a five point standard Kligman Scale: (0) skin is soft and moist; (1) skin appears normal with no visible dryness; (2) skin feels slightly dry to the touch with no visible flaking; (3) skin feels dry, tough, and has a whitish appearance with some scaling; and (4) skin feels very dry, rough, and has a whitish appearance with scaling. Evaluations can be made independently by two clinicians and averaged.

Skin Smoothness and Wrinkle Reduction Assay With Methods Disclosed in Packman et al. (1978): Skin smoothness and wrinkle reduction can also be assessed visually by using the methods disclosed in Packman and Gams (1978). For example, at each subject visit, the depth, shallowness and the total number of superficial facial lines (SFLs) of each subject can be carefully scored and recorded. A numerical score was obtained by multiplying a number factor times a depth/width/length factor. Scores are obtained for the eye area and mouth area (left and right sides) and added together as the total wrinkle score.

Appearance of Lines and Wrinkles Assay with Replicas: The appearance of lines and wrinkles on the skin can be evaluated using replicas, which is the impression of the skin's surface. Silicone rubber like material can be used. The replica can be analyzed by image analysis. Changes in the visibility of lines and wrinkles can be objectively quantified via the taking of silicon replicas form the subjects' face and analyzing the replicas image using a computer image analysis system. Replicas can be taken from the eye area and the neck area, and photographed with a digital camera using a low angle incidence lighting. The digital images can be analyzed with an image processing program and the are of the replicas covered by wrinkles or fine lines was determined.

Surface Contour of the Skin Assay with a Profilometer/Stylus Method: The surface contour of the skin can be measured by using the profilometer/Stylus method. This includes either shining a light or dragging a stylus across the replica surface. The vertical displacement of the stylus can be fed into a computer via a distance transducer, and after scanning a fixed length of replica a cross-sectional analysis of skin profile can be generated as a two-dimensional curve. This scan can be repeated any number of times along a fix axis to generate a simulated 3-D picture of the skin. Ten random sections of the replicas using the stylus technique can be obtained and combined to generate average values. The values of interest include Ra which is the arithmetic mean of all roughness (height) values computed by integrating the profile height relative to the mean profile height. Rt which is the maximum vertical distance between the highest peak and lowest trough, and Rz which is the mean peak amplitude minus the mean peak height. Values are given as a calibrated value in mm. Equipment should be standardized prior to each use by scanning metal standards of know values. Ra Value can be computed by the following equation: R_(a)=Standardize roughness; l_(m)=the traverse (scan) length; and y=the absolute value of the location of the profile relative to the mean profile height (x-axis).

Skin Clarity and Reduction in Freckles and Age Spots Assay: Skin clarity and the reduction in freckles and age spots can be evaluated using a Minolta Chromometer. Changes in skin color can be assessed to determine irritation potential due to product treatment using the a* values of the Minolta Chroma Meter. The a* value measures changes in skin color in the red region. This is used to determine whether a composition is inducing irritation. The measurements can be made on each side of the face and averaged, as left and right facial values. Skin clarity can also be measured using the Minolta Meter. The measurement is a combination of the a*, b, and L values of the Minolta Meter and is related to skin brightness, and correlates well with skin smoothness and hydration. Skin reading is taken as above. In one non-limiting aspect, skin clarity can be described as L/C where C is chroma and is defined as (a²+b²)^(1/2)

All of the skin-active ingredients, compositions, or methods disclosed and claimed in this specification can be made and executed without undue experimentation in light of the present disclosure. While the skin-active ingredients, compositions, or methods of this invention have been described in terms of particular embodiments, it will be apparent to those of skill in the art that variations may be applied to the skin-active ingredients, compositions, or methods and in the steps or in the sequence of steps of the method described herein without departing from the concept, spirit and scope of the invention.
